Japanese firm Yokogawa Test & Measurement has released its DLM3000HD series of compact, high-definition oscilloscopes for the development of next-generation automotive power electronics.

Positioned as a high-performance version of the DLM3000 series, the DLM3000HD series expands Yokogawa’s oscilloscope lineup with two models: the 500 MHz DLM3054HD and 350 MHz DLM3034HD. These deliver higher resolution for more accurate waveform analysis, and incorporate features designed to improve usability and simplify setup.

The oscilloscopes support multi-channel measurement, and improved resolution on the vertical axis offers greater measurement precision for next-generation power devices using silicon-carbide (SiC) technology, according to the company. The 12-bit vertical resolution is 16 times higher than that of the existing DLM3000 series, enabling the observation of minute changes in high-speed signals, such as during switching.

The serial bus analysis auto-setup function, which automatically sets the optimal bit rate and threshold level, can now also be used with previously captured waveforms. Auto-setup can be used for low-frequency signals, improving the efficiency of in-vehicle bus development and evaluation.

The DLM3000HD series has double the data storage capacity of the DLM3000 series, holding up to 1 billion points of acquired data. In addition to doubling the number of waveforms that can be searched and compared, a single device can measure the behavior of braking systems and other apparatuses at a sampling rate of up to 2.5 GS/s for several milliseconds, improving efficiency.
